Vash displays two different personalities. Vash usually exaggerates foolish characteristics to make people feel unthreatened and to hide his identity; for instance, exhibiting an almost obsessive love of doughnuts and at one point introduced himself as "Valentinez Alkalinella Xifax Sicidabohertz Gombigobilla Blue Stradivari Talentrent Pierre Andri Charton-Haymoss Ivanovich Baldeus George Doitzel Kaiser III". Vash's reputation as "The Humanoid Typhoon" is legendary, as is the damage and destruction associated with his presence. However, when those around him are threatened, Vash shows complete focus and control.Vash is a very multidimensional character -- quite literally a walking contradiction. He is often a womanizer, and other times a gentleman. Sometimes he is a coward, yet other times he shows great courage. He is a wanted man, yet he wouldn't hurt a fly. He also appears young, but is actually very old.
